UInt32.Parse Method (String)

Converts the string representation of a number to its 32-bit unsigned integer equivalent.

This method is not CLS-compliant.   The CLS-compliant alternative is Parse(String).

Not applicable.



A string representing the number to convert.

Return Value

A 32-bit unsigned integer equivalent to the number contained in s.

Exception typeCondition


The s parameter is a null reference (Nothing in Visual Basic).


The s parameter is not of the correct format.


The s parameter represents a number less than MinValue or greater than MaxValue.

The s parameter contains a number of the form:


Items in square brackets ('[' and ']') are optional, and other items are as follows.


Optional white space.


An optional positive sign.


A sequence of digits ranging from 0 to 9.

The s parameter is parsed using the formatting information in a NumberFormatInfo initialized for the current system culture. For more information, see NumberFormatInfo.CurrentInfo.

The following example demonstrates the Parse method.
